Abstract
The present disclosure provides a quantum dot material comprising a quantum dot body and a hole transport ligand bonded to the quantum dot body through a coordinate bond. The hole transport ligand comprises a carbazolyl group, at least one coordinating group and at least one crosslinking group having an unsaturated bond. Both of the coordinating group and the crosslinking group are terminal groups of the hole transport ligand, and the coordinating group provides the coordinate bond. The present disclosure also provides a method for manufacturing the quantum dot material, a light emitting diode and a display panel.
